Description

AT 401 272 BAT 401 272 B

Die Erfindung bezieht sich auf eine Dämmatte od. dgl. aus wenigstens zwei Lagen Vlies mit Naturfaserflor. Dämmatten aus Naturfasern zeichnen sich gegenüber künstlich hergestellten Dämmstoffen neben anderen Vorteilen eines Naturproduktes vor allem durch die höhere Temperaturstandfestigkeit, die bessere Atmungsaktivität, die guten feuchtigkeitsspeichernden und staubbindenden Eigenschaften aus, so daß sich durch den Einsatz solcher Dämmatten als Dämmstoff im Bauwesen ein überaus gesundes Raumklima erzeugen läßt. Allerdings bestehen die bekannten Dämmatten aus ein oder mehreren Lagen eines Vlieses mit gleichem Fasermaterial und gleichbleibender Struktur, so daß sich die erzielbaren Dämmeigenschaften kaum beeinflussen und nur bedingt an verschiedene Bedingungen anpassen lassen.The invention relates to an insulating mat or the like. From at least two layers of nonwoven with natural fiber pile. Insulation mats made of natural fibers are distinguished from artificially produced insulation materials, among other advantages of a natural product, above all by their higher temperature stability, better breathability, good moisture-storing and dust-binding properties, so that the use of such insulation mats as insulation material in the building industry creates an extremely healthy indoor climate leaves. However, the known insulation mats consist of one or more layers of a fleece with the same fiber material and structure, so that the achievable insulation properties can hardly be influenced and can only be adapted to different conditions to a limited extent.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Dämmatte od. dgl. der eingangs geschilderten Art zu schaffen, die sich trotz ihres natürlichen Ausgangsmaterials durch die Möglichkeit der Abstimmung ihrer Gesamteigenschaften auf unterschiedliche Anforderungen auszeichnet.The invention is therefore based on the object of eliminating these deficiencies and creating an insulating mat or the like. Of the type described, which, despite its natural starting material, is distinguished by the possibility of adapting its overall properties to different requirements.

Die Erfindung löst diese Aufgabe dadurch, daß wenigstens eine Lage aus Vlies mit lamellenförmig verlegtem Flor und eine Lage aus Vlies mit schichtenförmig verlegtem Flor vorgesehen sind.The invention solves this problem in that at least one layer of nonwoven with a lamellar pile and one layer of nonwoven with a layered pile are provided.

Durch ein Verlegen des Faserflors in Lamellenform entsteht ein Vlies mit im wesentlichen stehend orientierten Fasern, wodurch die Rohdichte gesenkt wird und eine leichte Verarbeitbarkeit der Vliese bei extremer Formstabilität erreicht wird, wozu noch eine geringe Wärmeleitfähigkeit, eine gute Schallabsorptionsfähigkeit und eine gewisse Brandsicherheit kommen. Durch ein schichtenförmig verlegtes Flor ergibt sich demgegenüber ein Vlies mit im wesentlichen liegend orientierten Fasern, womit ausgezeichnete Wärmedämmeigenschaften verbunden sind, so daß eine Kombination dieser unterschiedlichen Vliese auch zu einer Kombination der jeweiligen Vlieseigenschaften führt. Da sich diese Eigenschaften bestens ergänzen, wird ein die Einzeleffekte übersteigender Summeneffekt mit überraschend hochwertiger Dämmwirkung erzielt. Durch die bewußte Auswahl der Vlieslagen hinsichtlich Anzahl und Faserorientierung kann außerdem eine Naturfasermatte mit unterschiedlichen, an die jeweiligen Anforderungen gut angepaßten Eigenschaften hergestellt werden, wobei selbstverständlich diese Eigenschaften nicht nur durch die Faserorientierung, sondern auch durch die Faserart und -behandlung mitbestimmt werden, was diese Matte hervorragend zum Einsatz als Dämmatte, aber auch als Matratzen- oder Deckeneinlage usw. geeignet macht.Laying the fiber pile in lamellar form creates a nonwoven with fibers that are essentially oriented vertically, which lowers the bulk density and makes it easy to process the nonwovens with extreme dimensional stability, plus low thermal conductivity, good sound absorption and a certain level of fire safety. By contrast, a layer-laid pile results in a nonwoven with fibers lying essentially horizontally, which is associated with excellent thermal insulation properties, so that a combination of these different nonwovens also leads to a combination of the respective nonwoven properties. Since these properties complement each other perfectly, a sum effect that exceeds the individual effects is achieved with a surprisingly high-quality insulation effect. Through the deliberate selection of the nonwoven layers with regard to number and fiber orientation, a natural fiber mat can also be produced with different properties that are well adapted to the respective requirements, whereby these properties are of course not only determined by the fiber orientation, but also by the type and treatment of the fibers Mat is ideal for use as an insulation mat, but also as a mattress or blanket insert, etc.

Sind drei Vlieslagen vorgesehen, wobei das Vlies der mittleren Lage aus einem zu den Vliesen der äußeren Lagen unterschiedlich verlegten Flor besteht, ergibt sich eine Dämmatte od. dgl. in Form einer Sandwichplatte, wobei die Eigenschaften der Außenlagen überwiegen und sich dadurch auf rationelle Weise eine Naturfasermatte mit bestimmter Eigenschaftscharakteristik hersteilen läßt.If three nonwoven layers are provided, the nonwoven of the middle layer consisting of a pile laid differently from the nonwovens of the outer layers, an insulating mat or the like results in the form of a sandwich panel, the properties of the outer layers predominating and thus being rationally one Natural fiber mat can be manufactured with certain characteristics.

Vorteilhaft ist es, wenn die Vliese mit schichtförmig verlegtem Flor aus Pflanzenfasern, vorzugsweise Baumwolle oder Leinen, und die Vliese mit lamellenförmig verlegtem Flor aus Tierhaar, vorzugsweise Schafwolle, bestehen. Pflanzenfasern sind meist kürzere Fasern, die sich für eine Schichtenverbindung eignen, Tierhaar mit seiner meist größeren Länge wiederum läßt sich besser lamellenförmig verlegen, da für die Lamellenform eine entsprechende Faserlänge zum Erreichen der erforderlichen Verfestigung notwendig ist.It is advantageous if the nonwovens with a layered pile of vegetable fibers, preferably cotton or linen, and the nonwovens with a lamellar pile of animal hair, preferably sheep's wool. Vegetable fibers are usually shorter fibers, which are suitable for a layer connection, animal hair with its mostly longer length, in turn, is easier to lay in a lamellar form, since a corresponding fiber length is necessary for the lamella shape in order to achieve the required consolidation.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung sind bei einer Dämmatte od. dgl. eine mittlere Lage aus Baumwoll- oder Leinenvlies mit schichtförmig verlegtem Flor und zwei äußere Lagen aus Schafwollvlies mit lamellenförmig verlegtem Flor vorgesehen, so daß nicht nur die guten Wärmedämmeigenschaften des Baumwoll- oder Leinenvlieses mit den Eigenschaften der Stabilität und der geringen Rohdichte, der Schallabsorbierung und Atmungsaktivität, der Feuchtigkeitsspeicherung und Staubabweisung der Schafwollvliese kombiniert werden, sondern darüber hinaus auch noch das feuchtigkeitsempfindliche, leichter verrottbare Baumwoll- oder Leinenvlies als Innenlage durch die robusteren, widerstandsfähigen Schafwollvliese an der Außenseite geschützt wird.According to a particularly advantageous embodiment of the invention, a middle layer of cotton or linen fleece with a layered pile and two outer layers of sheep wool fleece with a laminate pile are provided in an insulation mat or the like, so that not only the good thermal insulation properties of the cotton or Linen fleece can be combined with the properties of stability and low bulk density, sound absorption and breathability, moisture retention and dust repellency of the sheep's wool fleece, but also the moisture-sensitive, more easily rotable cotton or linen fleece as an inner layer thanks to the more robust, resistant sheep's wool fleece on the outside is protected.

An sich könnten die Vlieslagen auf jede geeignete Art und Weise miteinander verbunden werden, doch empfiehlt sich, die Lagen durch ein mechanisches Verfestigungsverfahren, wie Nadeln, Nitschein od. dgl., miteinander zu verbinden, um nicht durch entsprechende chemische Bindemittel od. dgl. das Naturprodukt zu verfälschen.As such, the nonwoven layers could be bonded to one another in any suitable manner, but it is advisable to bond the layers to one another by means of a mechanical strengthening process, such as needles, nitrous oxide or the like, in order not to be prevented by appropriate chemical binders or the like Adulterate natural product.

In der Zeichnung ist eine erfindungsgemäße Dämmatte an Hand eines schematischen Querschnittes näher veranschaulicht.In the drawing, an insulation mat according to the invention is illustrated in more detail using a schematic cross section.

Eine Dämmatte 1 setzt sich in Art einer Sandwichplatte aus drei Vlieslagen 2, 3, 4 zusammen, wobei die beiden äußeren Lagen 2, 4 jeweils aus einem Vlies 5 mit lamellenförmig verlegtem Flor 6 aus Schafwolle bestehen und die mittlere Lage 3 aus einem Vlies 7 mit schichtenförmig verlegtem Flor 8 aus Baumwolle oder Leinen. Die Lagen 2, 3, 4 sind durch ein Vernadeln miteinander verbunden und können zur besseren Verfestigung mit Oberflächendeckschichten 9, beispielsweise ein Thermoplastgitter, versehen sein. 2An insulating mat 1 is composed of three nonwoven layers 2, 3, 4 in the manner of a sandwich panel, the two outer layers 2, 4 each consisting of a nonwoven 5 with a lamellar pile 6 made of sheep's wool and the middle layer 3 consisting of a nonwoven 7 layered pile 8 made of cotton or linen. The layers 2, 3, 4 are connected to one another by needling and can be provided with surface cover layers 9, for example a thermoplastic grid, for better consolidation. 2nd
